%QZ     QZ factorization for generalized eigenvalues.
%   [AA, BB, Q, Z, V] = QZ(A,B) for square matrices A and B,
%   produces upper triangular matrices AA and BB, matrices Q
%   and Z containing the products of the left and right trans-
%   formations, such that Q*A*Z = AA, and Q*B*Z = BB, and the
%   generalized eigenvector matrix V.
% 
%   The alphas and betas comprising the generalized eigenvalues
%   are the diagonal elements of AA and BB so that 
%   A*V*diag(BB) = B*V*diag(AA).
